Description

Inder Technik. sind Schmelzgefäße in Gebrauch, die mit Düsen zur Einführung von Gasen, z. B. von Sauerstoff, versehen sind. Diese Düsen sind starkem Verschleiß ausgesetzt, so daß man bemüht ist, sie zu kühlen. Zu diesem Zweck hat man schon vorgeschlagen, dem eingeblasenen Gas Dampf zuzusetzen, doch ist die erzielte Kühlung nicht ausreichend. Es wurde ein Verfahren und eine zur Ausübung desselben dienende Vorrichtung gefunden, wodurch eine ausgezeichnete Kühlung der Düse in -,ihrer ganzen Länge möglich ist.Indian technology. are melting vessels in use that have nozzles for introduction of gases, e.g. B. of oxygen, are provided. These nozzles are subject to heavy wear exposed so that one tries to cool them. For this purpose one already has suggested adding steam to the blown gas, but the achieved cooling unsatisfactory. There became one method and one for practicing the same Apparatus found whereby excellent cooling of the nozzle in -, its whole Length is possible.

Das Verfahren besteht im wesentlichen darin, daß das Innere der mit einer metallenen Auskleidung versehenen Düse fortlaufend mit Wasser benetzt wird. Durch die Gasbewegung wird das Wasser auf die ganze innere Wandung der Düse ausgebreitet und an dieser entlang getrieben. Die Verdampfungswärme des Wassers bewirkt, daß eine ausreichende Kühlung dei- Düse erzielt wird. .The process consists essentially in that the interior of the with a metal liner provided nozzle is continuously wetted with water. The gas movement spreads the water over the entire inner wall of the nozzle and driven along this. The heat of evaporation of the water causes Sufficient cooling of the nozzle is achieved. .

Eine Vorrichtung zur Ausübung des Verfahrens gemäß der Erfindung ist in der Abbildung schematisch dargestellt. Es ist i ein Rohr für die Gaszuführung, 2 eine im Innern desselben angeordnete Zuführung für Wasser, 3 ist die metallische Auskleidung der Düse, welche sich in einer feuerfesten Masse, die gestrichelt gezeichnet ist, befindet. Die Wirkungsweise der Vorrichtung besteht darin, daß durch den Gasstrom . iin Rohr i das durch die Zuführung 2 zugesetzte Wasser vorwärts getrieben wird, in Richtung der mit einer metallischen Auskleidung 3 versehenen Düse. Als Auskleidung verwendet man zweckmäßig Metalle, die gegen Sauerstoff beständig sind, z. B. Kupfer, Nickel u. dgl. Die Vorrichtung kann in verschiedener Beziehung abgeändert werden, z. B. können mehrere Einführungen für Wasser angeordnet sein, die sich zum Teil in der Zuführung und in der Düse befinden. Die Düse kann z. B. zur Einführung von Sauerstoff in Stahlschmelzen im Siemens-Martinofen, ferner auch für Konverter oder Elektroöfen verwendet werden.An apparatus for practicing the method according to the invention is shown schematically in the figure. There is a pipe for the gas supply, 2 a feed for water arranged inside it, 3 is the metallic one Lining the nozzle, which is in a refractory mass, which is shown in dashed lines is located. The operation of the device is that through the gas flow . iin pipe i the water added through feed 2 is driven forward, in the direction of the nozzle provided with a metallic lining 3. As a lining it is appropriate to use metals that are resistant to oxygen, z. B. copper, Nickel and the like. The device can be modified in various ways, z. B. several inlets for water can be arranged, which are partly in the feed and in the nozzle. The nozzle can e.g. B. to introduce Oxygen in steel melts in the Siemens Martin furnace, also for converters or Electric furnaces can be used.
